Marketing 2A (MAR02A2) Consumer Behaviour Notes (UJ) — Exam Notes for University of Johannesburg Students

Consumer behaviour is one of the most important foundations of marketing because it explains how and why people choose, use, evaluate, and dispose of products and services. In Marketing 2A (MAR02A2) at the University of Johannesburg (UJ), the topic is usually approached as a practical blend of psychology, social influence, culture, and decision-making. These notes bring together the core concepts, models, and exam-ready insights needed to understand consumer behaviour in a South African university context, with examples that help connect theory to real marketing practice.

1. Introduction to Consumer Behaviour

Consumer behaviour refers to the activities, thoughts, feelings, and decisions involved when individuals or groups select, purchase, use, and dispose of goods and services. It is not only about buying. It includes the complete process that starts when a consumer recognises a need and ends long after the purchase, because post-purchase satisfaction, complaints, repeat purchase, and word-of-mouth are also part of consumer behaviour. In marketing, understanding consumer behaviour is essential because it helps firms design products, set prices, choose distribution channels, and craft communication that fits the realities of the target market rather than relying on assumptions.

Why consumer behaviour matters in marketing

A marketer who understands consumers is in a much stronger position to create value. This is because consumers do not respond only to functional benefits such as durability or price. They also respond to emotions, symbols, social expectations, habits, cultural norms, and perceived risks. For example, two consumers may both buy smartphones, but one may focus on camera quality and battery life, while another may care mainly about social status, brand image, or the ability to use a specific app ecosystem. The same product can therefore satisfy different motivations in different ways.

Consumer behaviour matters for at least five reasons:

1. Market segmentation: Consumers differ in age, income, lifestyle, personality, and buying habits. Recognising these differences allows marketers to divide a market into meaningful groups.
2. Product design: Understanding consumer needs helps firms build products that solve real problems and offer relevant features.
3. Promotion: Advertising messages are more persuasive when they match consumer values, motivations, and level of knowledge.
4. Distribution: Consumers expect convenience, accessibility, and channel consistency, whether they shop in-store or online.
5. Customer retention: Satisfaction and loyalty depend on how the product performs relative to expectations, not only on the initial sale.

In the South African market, these reasons are especially important because consumers operate in very different economic realities. One consumer may shop using a debit card and compare prices across multiple retailers, while another may rely on informal markets, cash purchases, or value-oriented brands. The marketer must understand not just what people buy, but the context in which they buy.

The nature of consumer behaviour

Consumer behaviour is complex, dynamic, and multidimensional. It changes across time, social settings, and product categories. A person may behave carefully when buying a laptop but impulsively when buying snacks or fashion accessories. The level of involvement also changes: high-involvement purchases usually involve more research and deliberation, while low-involvement purchases may be routine or habitual.

Consumer behaviour is shaped by three broad types of influences:

• Individual influences such as motivation, perception, learning, beliefs, attitudes, and personality
• Social influences such as family, reference groups, social class, and culture
• Situational influences such as time pressure, physical surroundings, mood, and purchase context

These influences are not separate in real life. They interact. For example, a student with a strong desire to save money may still buy a branded item if friends see it as fashionable, or if a store promotion creates a feeling of urgency. Consumer behaviour therefore requires a holistic approach.

The marketing relevance of studying consumer behaviour

Marketers study consumer behaviour to answer practical questions such as:

• Why do consumers choose one brand over another?
• What makes them delay purchase?
• Why do some buyers stay loyal while others switch?
• How do consumers respond to price changes?
• Which social or cultural factors shape brand preferences?
• How can firms reduce perceived risk and increase trust?

These questions are central to product positioning, brand strategy, and customer experience. For instance, if a business discovers that consumers perceive a product as expensive even when the price is reasonable, it may need to improve value communication rather than lower the price. Similarly, if buyers fear poor after-sales service, the company may need to strengthen guarantees, service centres, or online support.

Key exam terms to remember

• Consumer: The person who uses or consumes the product, whether or not they are the buyer.
• Buyer: The person who makes the purchase.
• User: The person who actually uses the product.
• Consumption: The process of using a product or service to satisfy needs.
• Disposal: What consumers do with a product after use, such as reselling, recycling, or discarding it.

These distinctions are important in exams because not every buyer is the user. A parent may buy school shoes for a child, but the child is the user. In many households, purchase decisions are shared among several family members, each with different roles and influence.

2. Consumer Decision-Making Process and Problem Solving

The consumer decision-making process explains the sequence consumers usually follow when making a purchase. It is often described as a problem-solving model with five broad stages: need recognition, information search, evaluation of alternatives, purchase decision, and post-purchase evaluation. While real consumers do not always move neatly through every stage, the model provides a useful framework for understanding how marketing influences choices.

Stage 1: Need recognition

Need recognition occurs when a consumer notices a difference between the current state and the desired state. The current state is what the consumer has now; the desired state is what the consumer wants. The gap between the two creates motivation. This gap may be triggered internally or externally.

• Internal triggers: hunger, thirst, fatigue, boredom, discomfort, or a personal goal
• External triggers: advertisements, peer comments, store displays, price promotions, social media content, or product reminders

A simple example is a student whose laptop battery starts failing. The current state is unreliable performance, while the desired state is a device that supports studying, note-taking, and online learning. The need can also be psychological rather than functional. A consumer may buy new sneakers not because the old pair is unusable, but because of fashion, status, or identity expression.

Need recognition is important in marketing because brands try to be present at the moment a problem becomes conscious. A beverage brand may focus on refreshment, a fintech app may focus on convenience, and a cosmetics brand may focus on confidence or self-expression. The trigger determines whether the consumer enters the market at all.

Stage 2: Information search

Once a need is recognised, consumers search for information to reduce uncertainty. Information search can be internal or external.

• Internal search: Memory-based recall of past experiences, brand knowledge, or advertising exposure
• External search: Asking friends, reading reviews, comparing prices, visiting stores, checking websites, or using social media

The extent of search depends on several factors:

• Importance of the product
• Price and financial risk
• Familiarity with the product category
• Time available
• Perceived risk
• Personality and involvement level

For low-risk products such as toothpaste, consumers often rely on habitual or internal search. For high-risk products such as laptops, cars, or financial services, they may search extensively. In a South African context, consumers frequently use WhatsApp groups, Facebook comments, retailer websites, and comparison platforms to evaluate options. Word-of-mouth remains highly influential because it is perceived as more trustworthy than paid advertising.

Stage 3: Evaluation of alternatives

At this stage, consumers compare available options and form preferences. The evaluation is not always logical in a purely mathematical sense. Consumers may use a combination of objective criteria and emotional cues. These criteria can include:

• Price
• Quality
• Brand reputation
• Features
• Design
• Availability
• Peer approval
• Warranty
• Convenience
• Ethical image

Consumers may use different decision rules:

1. Compensatory rule: A weakness in one attribute can be offset by a strength in another. For example, a product may be more expensive but still chosen because it is perceived as higher quality.
2. Non-compensatory rule: A poor rating on one key attribute leads to rejection regardless of strengths elsewhere. For example, a consumer may refuse any laptop with insufficient battery life.
3. Lexicographic rule: The consumer chooses the brand that performs best on the most important attribute.
4. Satisficing: The consumer selects the first acceptable option rather than the absolute best option.

Marketers can influence this stage by managing the product’s attribute profile. If consumers value affordability and reliability, the brand should communicate those clearly. If consumers compare mainly through reviews, ratings, and social proof, the business must improve public reputation and visible evidence of quality.

Stage 4: Purchase decision

The purchase decision is the point at which the consumer chooses whether to buy, what to buy, when to buy, where to buy, and how much to buy. Even after a strong intention to purchase, final choice can still be affected by situational factors such as stock availability, store atmosphere, promotions, payment options, or unexpected budget pressure.

There is often a gap between intention and action. A consumer may want a product but postpone purchase because of:

• Financial constraints
• Fear of making the wrong choice
• Lack of trust in the seller
• Competing priorities
• Waiting for a sale or bonus
• Convenience issues

This is why point-of-sale marketing matters. A retailer can convert undecided shoppers through signage, sampling, bundling, financing options, or easy returns. In online environments, shopping cart design, delivery fees, and checkout simplicity can heavily influence final purchase.

Stage 5: Post-purchase evaluation

After purchase, consumers compare actual performance with expectations. This stage determines satisfaction, dissatisfaction, repeat purchase, complaint behaviour, and word-of-mouth. If performance meets or exceeds expectations, the consumer is likely to be satisfied. If performance falls short, dissatisfaction and cognitive dissonance may occur.

Cognitive dissonance is the uncomfortable feeling that results when a consumer questions whether the purchase was the correct one. It is especially common after expensive, important, or irreversible purchases. Marketers reduce dissonance through reassurance, warranties, follow-up messages, user guides, customer support, and evidence that the purchase was wise.

Post-purchase behaviour matters because it affects long-term customer value. A satisfied customer may buy again and recommend the brand, while a dissatisfied customer may complain publicly or switch to competitors. In the age of digital communication, one bad experience can influence many potential buyers through reviews and social media.

Levels of consumer problem solving

Consumer decision-making can be grouped into three levels:

Level of problem solving	Characteristics	Typical products
Routinised response behaviour	Low involvement, habitual, little search	Soap, bread, salt, basic toiletries
Limited problem solving	Some search, moderate involvement, familiar category	Clothing, small appliances, casual dining
Extended problem solving	High involvement, extensive search, careful comparison	Cars, houses, laptops, insurance, education services

Marketers must match strategy to the level of problem solving. A shampoo brand may rely on shelf visibility and brand familiarity, while a car brand may require detailed technical content, test drives, and dealer support.

3. Psychological Influences on Consumer Behaviour

Psychological factors are central to consumer behaviour because they explain how consumers notice information, interpret it, remember it, and turn it into action. Even when two consumers are exposed to the same advertisement, they may perceive it differently due to prior beliefs, current needs, mood, learning history, or personality. Marketing succeeds when it works with, rather than against, these psychological realities.

Motivation

Motivation is the internal force that drives a person to act in order to satisfy a need. Needs may be physiological or psychological. Physiological needs include food, water, shelter, and rest. Psychological needs include belonging, esteem, achievement, and self-expression. A consumer rarely buys only because of one type of need. Many purchases satisfy multiple motives at once.

A useful way to think about motivation is through needs, goals, and behaviour:

1. A need creates tension.
2. The consumer seeks a goal that reduces the tension.
3. Behaviour is directed toward that goal.
4. Goal attainment brings satisfaction, temporarily reducing the need.

For example, a consumer may purchase running shoes for fitness, health, social identity, and personal achievement. The same product may also satisfy emotional desires such as confidence or self-discipline. Marketers strengthen motivation by linking products to meaningful goals, not just features.

Perception

Perception is the process by which consumers select, organise, and interpret stimuli to create a meaningful picture of the world. Marketing communications do not automatically work simply because they are sent. Consumers filter them through perceptual processes.

Key perceptual concepts include:

• Selective attention: Consumers notice only some of the many stimuli around them.
• Selective distortion: Consumers interpret information in a way that fits existing beliefs.
• Selective retention: Consumers remember only some information after exposure.

This explains why two consumers can see the same price promotion and react differently. One may focus on the discount, while another may suspect poor quality. Perception is also influenced by sensory cues such as colour, sound, packaging, texture, and smell. A premium-looking package may create a higher quality impression even before the product is used.

In practice, marketers use perception carefully. A clean layout, clear claims, recognizable branding, and consistent visual identity can all reduce confusion and increase trust. However, exaggerated claims can backfire if consumers perceive them as misleading.

Learning

Learning refers to changes in behaviour resulting from experience. Consumers learn from direct use, observation, memory, repetition, and reinforcement. If a consumer buys a detergent and it performs well, the positive experience reinforces repeat purchase. If the product fails, the consumer may switch brands and remember the failure for future decisions.

Two important learning ideas are:

• Classical conditioning: A neutral stimulus becomes associated with a meaningful stimulus. For example, a brand may use music, colours, or celebrity imagery repeatedly until consumers connect the brand with a specific emotion.
• Operant conditioning: Behaviour is shaped by rewards and punishments. Discounts, loyalty points, free samples, and recognition can reinforce desired consumer behaviour.

Learning is one of the reasons consistency matters in branding. Consistent experiences build favourable associations over time. If a restaurant repeatedly offers good service, consumers learn to expect reliability. If service is inconsistent, trust weakens.

Memory

Memory is crucial because consumers rely on stored information when making choices. Marketing can influence memory by using repetition, distinctive packaging, slogans, emotional stories, and frequent exposure. A brand that is easy to recall at the moment of purchase has an advantage, especially in crowded markets.

Memory includes:

• Short-term memory: temporary holding of information
• Long-term memory: more durable storage of facts, feelings, and experiences

The goal of marketing is not only awareness but also retrieval. A consumer may know many brands, yet only the brands that come easily to mind during decision-making are likely to enter the consideration set.

Attitudes

An attitude is a learned, relatively enduring evaluation of an object, idea, person, or issue. Attitudes have three components:

1. Cognitive: beliefs and thoughts
2. Affective: feelings and emotions
3. Conative: behavioural intention

A consumer may believe a brand is affordable, feel positively toward it, and intend to buy it. Marketers often try to change one or more of these components. For example, a campaign may provide facts to shift beliefs, use emotional appeals to generate positive feelings, or provide special offers to encourage trial.

Attitudes matter because they are linked to behaviour, although the link is not always perfect. Consumers may have a positive attitude toward healthy eating but still buy unhealthy snacks under stress or convenience pressure. This gap between attitude and behaviour is important in exam answers because it shows that attitudes influence, but do not fully determine, action.

Personality and self-concept

Personality refers to consistent patterns of behaviour, thinking, and feeling that distinguish one person from another. Marketers often use personality to segment markets or to build brand personality, the human-like traits associated with a brand. A brand may be seen as adventurous, sophisticated, reliable, youthful, or rugged.

Self-concept is a consumer’s view of who they are and who they want to be. Consumers often choose products that support their identity. This is why people buy clothing, cars, accessories, and even digital devices as symbols of self-expression. Brands that reflect or enhance identity may feel more relevant than brands that only offer functional benefits.

Involvement and risk

Involvement refers to the degree of personal relevance and interest a consumer feels toward a product or decision. High-involvement products usually require more thought, while low-involvement products are often bought quickly and habitually. Risk is closely linked to involvement.

The main types of perceived risk are:

• Functional risk: the product may not perform properly
• Financial risk: money may be wasted
• Physical risk: the product may cause harm
• Social risk: others may judge the purchase negatively
• Psychological risk: the purchase may damage self-image
• Time risk: time may be wasted in researching or replacing the product

Marketers lower perceived risk through warranties, money-back guarantees, certification, testimonials, trial periods, and strong customer service. The more risky the product feels, the more reassurance consumers need.

4. Social, Cultural, and Situational Influences

Consumer behaviour is deeply social. People do not make choices in isolation; they are influenced by family, peers, social roles, status expectations, and broader cultural systems. In many cases, the strongest market forces are social rather than purely economic. A consumer may buy a product because it fits a group identity, signals belonging, or aligns with the values of a community.

Reference groups and opinion leaders

A reference group is any group that serves as a point of comparison or influence in shaping attitudes and behaviour. Reference groups can be:

• Primary groups such as family and close friends
• Secondary groups such as work colleagues, clubs, or professional associations
• Aspirational groups that consumers want to join
• Dissociative groups that consumers want to avoid

Opinion leaders are influential people whose views affect others’ choices. In modern marketing, opinion leaders may include influencers, content creators, experts, classmates, local community figures, or trusted friends. Their power comes from credibility, expertise, similarity, and social visibility. For example, a student may trust a peer’s review of headphones more than a television advertisement, especially if the peer has similar usage needs.

Marketers use reference groups by encouraging testimonials, user-generated content, social proof, and ambassador campaigns. The key is authenticity: if consumers sense that an endorsement is unnatural or purely paid, persuasion weakens.

Family influence and household decision-making

Family is one of the most important influences on consumer behaviour because households often make purchases collectively. Family members may play different roles:

• Initiators: suggest the idea
• Influencers: shape preferences
• Deciders: choose what will be bought
• Buyers: make the actual purchase
• Users: consume the product

These roles may overlap. In some households, the same person performs several roles. In others, especially for expensive or high-risk items, decision-making is shared. Family influence is strong in categories such as food, clothing, education, furniture, transport, and healthcare.

Family life cycle also matters. A single student, a young couple, a growing family, and an older household may have very different needs, budgets, and priorities. A marketer who ignores household structure may miss the real decision maker.

Social class

Social class refers to relatively stable divisions within society based on income, education, occupation, and related social prestige. It influences taste, access, shopping patterns, leisure choices, and brand preferences. Social class does not determine individual behaviour completely, but it provides a strong patterning effect.

In practice, social class affects:

• Store choice
• Sensitivity to price
• Response to premium versus value branding
• Product categories considered “appropriate”
• Use of services such as private healthcare, education, and financial products

South African marketers often need to account for wide inequality and different levels of market access. A single national campaign may not resonate equally across all segments unless it is carefully adapted for affordability, language, and lifestyle context.

Culture and subculture

Culture is the set of learned values, beliefs, customs, and symbols shared by a society. It shapes what people consider normal, desirable, respectful, or unacceptable. Because culture is learned, it influences consumer behaviour over time and across generations.

Subcultures are smaller groups within a larger culture that share distinct values or experiences. Examples include language groups, religious communities, age cohorts, and regional communities. Subcultures can have important buying patterns because they may prefer certain foods, dress styles, media platforms, or brands.

Marketers need cultural sensitivity because messages that seem neutral in one setting may be inappropriate or ineffective in another. This is especially important in multilingual and diverse markets. Product naming, colour symbolism, humour, and family imagery can all carry different meanings depending on the audience.

Situational influences

Situational factors are temporary circumstances that affect consumer behaviour at a particular moment. They can change the purchase decision even when the consumer’s general preferences remain constant.

Important situational influences include:

• Physical surroundings: store layout, lighting, music, crowding, cleanliness
• Social surroundings: who is present during the decision
• Time pressure: whether the consumer is rushed
• Task definition: whether the purchase is for personal use, a gift, or a business need
• Mood and temporary state: stress, excitement, fatigue, hunger
• Momentary conditions: weather, stock availability, payment friction, transport access

A consumer may choose a restaurant because it is near campus, even if another restaurant is preferred in theory. A shopper may switch brands because the usual one is out of stock. These small situational factors can produce large market effects. That is why retail layout, queue management, and channel convenience are not minor details; they directly shape behaviour.

The South African context

Consumer behaviour in South Africa is shaped by economic diversity, urban-rural differences, digital adoption, and a strong mix of traditional and modern consumption patterns. Many consumers are value-conscious and highly responsive to promotions, but they also care about quality, trust, and convenience. Social media influences are strong, yet word-of-mouth remains powerful in many communities. Brands that succeed usually combine accessibility, relevance, and respect for local realities.

Situational factors	Affect final purchase moment	Improve store, online, and service experience

5. Market Segmentation, Consumer Types, and Exam Application

Consumer behaviour becomes most useful in marketing when it is applied to segmentation, targeting, positioning, and communication strategy. The purpose of studying consumer behaviour is not only to describe people but to build better marketing decisions. In exams, strong answers show that the student can connect theory to strategic action.

Consumer segmentation based on behaviour

Behavioural segmentation divides consumers according to how they behave, not only who they are. This includes usage rate, loyalty, benefits sought, occasion, and readiness stage.

Usage rate

Consumers may be classified as heavy, medium, light, or non-users. Heavy users are often small in number but contribute a large share of sales. A brand may need to retain them carefully because they are economically important. Light users may be easier to reach with convenience messaging or reminder marketing.

Loyalty status

Consumers differ in loyalty:

• Hard-core loyal: always buy one brand
• Split loyal: divide purchases among a few brands
• Shifting loyal: change brands often
• Switchers: no consistent pattern

Loyalty matters because it affects lifetime value and promotion strategy. A loyal customer may respond more to service quality and relationship benefits, while a switcher may respond more to price or novelty.

Benefits sought

Consumers often choose products for different reasons. For example, one consumer may want a phone for battery life, another for camera quality, another for affordability, and another for prestige. This is why one product category can support multiple sub-brands or positioning strategies.

Occasion-based behaviour

Some products are used for specific occasions, such as celebrations, holidays, work, sport, or gift-giving. Occasion-based segmentation helps marketers match promotions to moments of need.

Types of consumer purchase behaviour

Consumer purchase behaviour is commonly classified into four types:

Type of behaviour	Involvement level	Difference between brands	Example
Complex buying behaviour	High	Large	Car, laptop, insurance
Dissonance-reducing behaviour	High	Small	Tiles, insurance-like services, appliances
Habitual buying behaviour	Low	Small	Salt, soap, sugar
Variety-seeking behaviour	Low	Large	Snacks, soft drinks, fashion items

This classification helps marketers understand what kind of influence works best. Complex buying requires information, comparison, and reassurance. Habitual buying needs availability, visibility, and consistency. Variety-seeking often benefits from promotions, packaging changes, and novelty.

Decision-making roles in consumer purchases

A single purchase may involve several roles:

• Initiator: first suggests the need
• Influencer: provides advice or opinion
• Decider: chooses the product
• Buyer: makes the payment
• User: consumes the product
• Gatekeeper: controls access to information or purchase opportunities

These roles matter because marketing messages may need to address different people. In family purchases, a child may influence snack choice, a parent may decide the budget, and another parent may buy the product. In business services, a manager may decide, finance may approve, and end users may evaluate the outcome.

How to answer exam questions effectively

A strong exam answer in consumer behaviour should do more than define terms. It should:

1. Define the concept clearly.
2. Explain the underlying process.
3. Show the marketing implication.
4. Use a practical example.
5. Link the idea to South African or UJ-relevant context where appropriate.

For example, if asked about perception, it is not enough to say that perception is how consumers interpret stimuli. A strong answer explains selective attention, selective distortion, and selective retention, and then shows how packaging, advertising, and brand familiarity influence whether a consumer notices and remembers a message.

Common exam-style short notes

Consumer behaviour

The study of how individuals and groups select, buy, use, and dispose of products, services, ideas, or experiences to satisfy needs and wants.

Motivation

The inner drive that causes a consumer to act in order to reduce tension or satisfy a need.

Attitude

A learned, enduring evaluation of an object or idea that includes cognitive, affective, and behavioural components.

Perceived risk

The consumer’s expectation that a purchase may result in loss, dissatisfaction, or harm.

Reference group

A group that influences a person’s attitudes or behaviour through comparison or direct pressure.

Learning

A change in behaviour based on experience, repetition, and reinforcement.

Practical South African examples for revision

A South African consumer deciding between prepaid data bundles may consider price, network reliability, bundle size, and social influence. If friends use a particular network, that reference group effect may shape the choice. If the consumer has previously experienced weak coverage, learning and perception may produce brand avoidance. If the consumer sees a limited-time promotion, the situational influence may accelerate the purchase. This shows how several concepts operate together.

Another example is grocery shopping. A household may use habitual buying for staples like maize meal, rice, and soap, but extended problem solving for school fees, appliances, or insurance products. A retailer that understands this can design both quick convenience aisles and detailed information support in higher-involvement categories.

Final exam revision points

• Consumer behaviour is shaped by psychological, social, cultural, and situational factors.
• The consumer decision-making process includes need recognition, information search, evaluation, purchase, and post-purchase behaviour.
• Consumers are not always rational; they use shortcuts, habits, emotions, and social cues.
• Marketers must understand involvement, risk, reference groups, culture, and attitudes.
• Effective marketing matches strategy to the type of consumer decision and the context of purchase.

High-value conclusion for revision

Consumer behaviour is the bridge between theory and practice in marketing. It explains why consumers respond differently to the same stimulus, why some products become habits and others require careful thought, and why social and cultural contexts can be more influential than price alone. For MAR02A2 at UJ, mastering consumer behaviour means being able to describe the models clearly, apply them to real examples, and explain how marketers use these insights to create value, reduce uncertainty, and build long-term relationships with consumers.
